Strange crash in pushbuild in 6.0-rpl. The failures happened consistently on win2003-x86/embedded in completion_type_func and innodb_autoinc_lock_mode_func, in every push from https://intranet.mysql.com/secure/pushbuild/showpush.pl?dir=bzr_mysql-6.0-rpl&order=61 to https://intranet.mysql.com/secure/pushbuild/showpush.pl?dir=bzr_mysql-6.0-rpl&order=66 . It also happened in 5.1-rpl, between the same changesets. It did not happen at a ny other platform, time, or tree.

So it may look like the bug is already fixed. However, there are two candidate pushes that could have fixed it: https://intranet.mysql.com/secure/pushbuild/showpush.pl?dir=bzr_mysql-6.0-rpl&order=67 and https://intranet.mysql.com/secure/pushbuild/showpush.pl?dir=bzr_mysql-6.0-rpl&order=68 . None of these changed the server (only tests). So the crash can probably still be triggered.

The error message is:

How to repeat:
https://intranet.mysql.com/secure/pushbuild/showpush.pl?dir=bzr_mysql-6.0-rpl&order=66 win2003-x86/embedded
xref: http://tinyurl.com/4x3p9g

Suggested fix:
The push at https://intranet.mysql.com/secure/pushbuild/showpush.pl?dir=bzr_mysql-6.0-rpl&order=67 modified the two failing tests, changing some queries from lowercase to uppercase. That's the only thing that seems remotely related to the crash. I suggest reverting the changset of https://intranet.mysql.com/secure/pushbuild/showpush.pl?dir=bzr_mysql-6.0-rpl&order=67 in these two files and see if the error comes back.

Calvin is our Windows and also 6.0 expert. Interesting question, what are the names of the two files changed between the version.
[20 Oct 2008 17:48] Mikhail Izioumtchenko
Not a bug because as far as I understand 6.0-rpl is a branch private to MySQL, but please correct me if I'm wrong.
[20 Oct 2008 17:56] Mikhail Izioumtchenko
removing assignment, setting back to 'Veified' because it's still probably a bug from MySQL's standpoint, but changing the area to replication (per Calvin)

We can't repeat this failure.  Closing bug as "Can't repeat".
